Project description:We hypothesize that gene expression in the CBs of these two strains of mice are divergent thus contributing to the disparity in the phenotypes. More specifically, (1) genes related to CB function are expressed less in the A/J mice compared to DBA/2J mice; (2) gene expression levels of morphogenic and trophic factors of the CB maybe significantly lower in the A/J mice than the DBA/2J mice. In order to test these hypotheses, we utilized microarray analysis to examine transcriptional differences between CBs of both strains of mice. Keywords: comparative expression profiling

Project description:Genetic background shifts the severity of muscular dystrophy. In mice, the DBA/2J strain confers a more severe muscular dystrophy phenotype, whereas the Murphy’s Roth Large (MRL) strain has “super-healing” properties that reduce fibrosis. A comparative analysis of the Sgcg null model of Limb Girdle Muscular Dystrophy in the DBA/2J versus MRL strain showed the MRL background supported greater myofiber regeneration with reduced structural degradation of muscle. Transcriptomic profiling of dystrophic muscle in the DBA/2J and MRL strains indicated strain-dependent expression of the extracellular matrix (ECM) and TGF-b signaling genes. To investigate the MRL ECM, cellular components were removed from dystrophic muscle sections to generate decellularized “myoscaffolds”. Decellularized myoscaffolds from dystrophic mice in the protective MRL strain had significantly less deposition of collagen and matrix-bound TGF-b1 and TGF-b3 throughout the matrix. Dystrophic myoscaffolds from the MRL background were enriched in myokines. C2C12 myoblasts were seeded onto decellularized matrices from Sgcg-/- MRL and Sgcg-/- DBA/2J matrices. Acellular myoscaffolds from the dystrophic MRL background induced myoblast differentiation and growth compared to dystrophic myoscaffolds from the DBA/2J matrices. These studies establish that the MRL background also generates its effect through a highly regenerative ECM, which is active even in muscular dystrophy.

This study utilizes microarray analysis to test these hypotheses. Three sets of CBs were harvested from both strains. RNA was isolated and used for global gene expression profiling (Affymetrix Mouse 430 2.0 array). Statistically significant gene expression was determined as a minimum 6 counts of 9 pairwise comparisons, minimum 1.5-fold change, and p < 0.05.
